Abstract: Mobile Ad hoc Networks is a collection of wireless mobile nodes, which form temporary networks without relying on any existing infrastructure or centralized administration or standard support services regularly available in wide area networks to which the host may normally be connected. In this Paper we proposed a model i.e. Normalized Weighted Queue Model that was compared with other models and results are shown using NS2 Simulator.

Abstract: Cloud computing is one of the most influential paradigms in the IT industry in recent years. Since this technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. In order to realize scalable, flexible, and fine-grained access control of outsourced data in cloud computing, a hierarchical attribute-set-based encryption has been proposed (HASBE) with a hierarchical structure of users. The novel method of HASBE introduces in term of delegation mechanism and improved efficiency. It provides efficiently share confidential data on cloud servers and also involves in full delegation. The delegation defines that it involved for the transfer of authority under server permission.
